Last comment about VU Games seems, oh, biased?
[edit] How large are they?
The article says "Vugs are small to medium-sized cavities."
- Does a 1mm cavity in a rock qualify as a "vug?"
- What about a 1 meter cavity?
- What are the minimum to maximum size ranges?
- What are the typical size ranges?
- If a cavity is smaller than the minimum for a vug then does it have a name?
- If a cavity is larger than the maximum for a vug then does it have a name?
- Does the cavity need to be lined with crystals and/or minerals of a different type as the main rock to qualify as a vug?
- What if it's apparent there was a cavity at one time but it's now solid crystals? For example, sometimes I'll see a rock that has a pocket of crystals but there no remaining cavity. Is that still a "vug?" Marc Kupper (talk) (contribs) 17:04, 29 August 2007 (UTC)
A couple more...
- If a vug with crystals forms and later gets filled with debris (sand or other material working it's way into the cavity) then it is still a vug?
- Does the cavity need to be filled with gas (air?). If it's filled with water then is it still a vug? Marc Kupper (talk) (contribs) 22:04, 31 August 2007 (UTC)
